Abstract
A wide band matching network for power amplifier impedance matching, the wide band matching network comprising: a power amplifier transistor connected to an output network; the output network including: a series capacitor; an on-chip transformer connected to the capacitor in series, wherein the transformer and the capacitor act as a second order filter; and a port connected to the capacitor and a receiver switch.
Claims20
A wide band matching network for power amplifier impedance matching, the wide band matching network comprising:
- a power amplifier transistor connected to an output network;
- the output network including:
- a series capacitor;
- an on-chip transformer connected to the capacitor in series, wherein the transformer and the capacitor act as a second order filter;
- and
- an antenna port connected to the capacitor and a receiver switch,
- wherein the series capacitor, the receiver switch, and the antenna port are connected at a common node.
A method for operating a power amplifier network, the method comprising:
- determining whether to operate the power amplifier network in a power amplifier on/receiver-off mode or a power amplifier-off/receiver-on mode;
- when the power amplifier-on/receiver-off mode is selected, ensuring the power amplifier is on and a receiver switch is off, and performing power amplifier impedance matching;
- and
- when the power amplifier-off/receiver-on mode is selected, ensuring the power amplifier is off and the receiver switch is on, wherein the power amplifier network acts as impedance to prevent signal from entering the power amplifier network.
A system for operating a power amplifier network, the system comprising:
- a processor;
- and
- a memory storing non-transitory processor-executable instructions that, when executed by the processor, cause the processor to:
- determine whether to operate the power amplifier network in a power amplifier on/receiver-off mode or a power amplifier-off/receiver-on mode;
- when the power amplifier-on/receiver-off mode is selected, ensure the power amplifier is on and a receiver switch is off, and perform power amplifier impedance matching;
- and
- when the power amplifier-off/receiver-on mode is selected, ensure the power amplifier is off and the receiver switch is on, wherein the power amplifier network acts as impedance to prevent signal from entering the power amplifier network.
